CHARLES W.- TURNER, OF BROOKLYN, NEW YORK.

OXY-HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 746,409, dated December 1903- Applioation filed March 10, 1903.' Serial No. 147,047. (No model.)

' citizen of the United States,residin g at Brooklyn, in the county of Kings and State of New York, have invented certainnew and useful Improvements in Oxyhydrocarbon-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for gencrating and burning oxyhydrocarbon vapor or gas under high heat and pressure for heating steam-boilers, domestic stoves, and furnaces or for supplying heat wherever, required for'manufacturing purposes.

The object of my invention is to provide for rapidly and economically generating combustible vapor or gas of high calorific value and burning the same for domestic heating and cooking and for supplying high heat for metallurgic and other purposes by vaporizing hydrocarbon oil and water, each in a separate coil of pipe, under high heat and pressure, then combining the resulting superheated steam and hydrocarbon vapor and subjecting them to continued heat and pressure in a combining and fixing coil till a combustible oxyhydrocarbon vapor or gas of high. calorific value is produced, then burning it in contact with the coils in a steam-boiler furnace or.-

other place where the heat is utilized.

The particular matter in the construction and arrangement of the coils and connections constituting my invention will be defined in the claims. V

I will now describe the details of construc tion and operation of my improved heating apparatus by reference to the accompanying drawings, in whichi v Figure 1 represents a top plan view of the generating coils, showing the connecting fluid-supply pipes. Fig. 2 represents a front elevation thereof with the supply-pipes in section. Fig. 3 represents a side elevation as seen looking toward the left-hand side in Fig. 1. Fig. 4 represents a side elevation of the apparatus, partly in section, showing the coils in the fire-box of a steam-boiler and the supply-tanks.

My apparatus for generating and burning 'to the vaporizing-coils. .vided at the top with an inlet-pipe A, having a stop-cock through which hydrocarbon oil oxyhydrocarbon vapor or gas may be placed in the fire-box of a steam-boiler furnace, as shown in Fig. 4, or in any place where a high heat is desired. The vapor-generator is preferably constructed of two columns of heavy wrought-iron or steel coils composed of two vaporizing-coils and one combining and superheating-coil, having suitable supply-pipes for water and hydrocarbon oil and connections provided with stop-cocks and checkvalves. The hydrocarbon-oil tank A and the water-tank B are mounted on supports X X and may be at a suitable height to feed liquids to the coils by gravity, if desired, but are preferably supplied with air under pressure for forcing the liquids under pressure The tank A is promay be supplied or to which a pipe leading from an air-pump may be attached for admitting air under pressure for forcing oil under the desired pressure to the vaporizing-coil. A similar inlet-pipe and stop-cock B is attached to the top of tank B for admitting waterand air, thelatter being forced from an airpump for forcing the water under the desired pressure to its vaporizing-coil. The water-feed pipeb connects near the bottom of tank B and a is provided near the tank with a stop-cock b and near the generatingcoil or furnace with the check-valve b and the regulating stopcook 12. The supply-pipe b connects with the base of the water-vaporizing coil 0. The oil-feed pipe a connects with the oil tank A near its bottom and with the base of the oilvaporizing coil D and is provided near the tank with a stop-cock a and near the coil or furnace with the check-valve a and the regulating stop-cock a'. A drain-pipe having stop-cock n connects by a T-fitting with the water-feed pipe b for drawing ofi water.from the coil 0. The water-vaporizing coil C and oil-vaporizing coil D are preferably arranged one above the other in a column, as shown in Figs. 3 and 4. The vapor combining and superheating coil E is placed adjacent to the coils C and D, and the coils are properly connected for forcing superheated steam and oil vapor through a mixing-pipe and thence into the combining and superheating coil. The coils are made of heavy wrought-iron or steel with extra-thick Walls to withstand the inc, which connects by a T-fittiug with the mixing-pipe which in turn connects by the T-fitting d with the coil E. An oil-vapor pipe d leads from the top of coil D and connects with said T-fitting d, asshown in Fig. 1. The mixing-pipefis provided with a stopcock f for the blow-off pipe 72, a check-valve f, and a controlling-valvef. At the base of coil E the outlet-pipe e is bent upward and passed through the interior of the coil and at the top is bent over and passed down through the interior of coils O and D and atits lower end connects by a T-fitting g with the burner-pipe G, as shown in Fig. 2. This burner-pipe is made with two branches connecting with the fitting g and provided at their outer turned-up ends with the burners g and g, which are located centrally below the coils O and E, as indicated in Fig. 2. The pipe h, Fig. 4, is used for blowing oif the excess of steam when desired. As shown in Fig. 4, the oxyhydrocarbon generator and burner may be located in the fire-box K of a steam-boiler H, and in practice it will be located in domestic hot-air furnaces or the furnaces of steam or hot-water heating systems.

The apparatus having been constructed and connected as above described and the tanks A and B respectively filled with hydrocarbonoil and water, the operation of generating oxyhydrocarbon vapor or gas may be conducted as follows: Air is forced under the desired pressure through the inlet-pipes and stop-cocks A and B into the space into the tanks above the oil and water until the proper pressure is attained, as indicated by the gages w and to. In starting the operation only a small quantity of oil is at first admitted to the vaporizing-coil D, and then the supply is shut 01f. The stop-cock a is fully opened, permitting oil to fiow through pipe a, and the stop-cock a is partly opened for controlling the supply of oil admitted to the coil D. A sufficient supply of oil having been admitted to the coil D, the stop-cock a' is closed and a torch or other flame is burned in the interior of the columns of coils until the oil in the coil D is vaporized, and the vapor flows to the burners g g and is ignited. The vapor is burned sufficiently long to heat the coils red-hot. The stop-cock b is now fully opened, and the stop-cock b is partly opened for controlling the supply of water which is admitted to the base of the Water-vaporizing coil 0. The relative proportions of water and oil admitted to the coils O and D will be regulated by the stop-cocks a and b' for making oxyhydrocarbon vapor or gas of the desired calorific value. The steam generated in coil C passes oil. by pipe 0 and is therein superheated and discharged through pipe 0" into the mixing-pipe f. The hydrocarbon vapor generated in coil D flows from the top thereof through pipe 01 into mixing-pipefat the T-fittiug d in front of the steam-inlet. The superheated steam entering behind the oil-vapor under high pressure carries the latter through the combining and superheating coil E, where decomposition and recomposition are partly or wholly effected, with the result that oxygen of the water-vapor combines with carbon of the hydrocarbon to form carbon-monoxid gas and liberates hydrogen from the water-vapors. The gases and vapors pass from coil E through the pipe 6 in the interiors of the two columns of coils, where they are subjected to a still higher heat, thereby completing the chemical reactions and making fixed oxyhydrocarbon gas, which flows under high pressure to the burners g and g, Where perfect combustion takes place, producing very strong hot flames, which pass through and beyond the columns of coils and serve to heat a steam-boiler or other furnace to a high temperature.

The check-valves a and I) prevent the return of oil and Water through the feed-pipes a and b, and the check-valve f prevents the return of steam or gas through the mixingpipe f. g

The gas-outlet pipe 6 passed through the interiors of the coils and connecting with the burner-pipe I have found to be an important feature, since the gas and vapors are thereby subjected to the higher heat, and therefore fixed, so that they burn steady and with a strong flame at the burners. This arrangement overcomes the liability of the flames being extinguished at the burners, owing to sudden expansion and violent pressure of vapors and gases in the coils.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
